7.3.3 ParameterDescriptorType
The ParameterDescriptorType [OR9] [OR10] defines the input a client has to provide for setting ordering options. One instance of this type represents one order option to be set for the specified order
item.
The ParameterDescriptorType is an extension of a swe:AbstratDataComponentPropertyType see §7.2.3 and 8.2.1 in [OR11]. It is an “AbstractDataComponent” complex type so an abstract base class for all
components that in this context are order options. Each option can be: optional or mandatory, if the parameter can or shall be provided by the client.
updatable or not, “updateable” is defined in the SPS specification, but in this context has to be set always false because update operation is not supported in ordering service.
Figure 7-2 - ParameterDescriptorType diagram.
Using swe entities each option can be identified by an entity simple or complex as shown in Figure 7-3 and Table 7-5.
